IMPROVEMENT IN DOOR-LATCHES.

Specification forming part of Letters Patent No. 144,288, dated November4, 1873 application filed August 9, 1873.

@Asn C.

To all whom it may concern:

Be it known that I, ORIN B. RAND, of Kalamazoo, in the county ofKalamazoo and State of Michigan, have invented a new and usefulImprovement on my Improved Door-Latch, for which Letters Patent of theUnited States were issued June 24, 1873, No. 140,307.

My improvement consists in arranging my patented invention, abovereferred to, so as to attach it to the face of the door, and fasten itat the top and bottom, or either, as desired, and is particularlyadapted to large double doors.

I construct my door-fastener, as improved, for the purpose abovementioned, as shown in the drawings, Figure 1 representing a front view,as incased and attached to the door; Fig. 2, a front view, showing theworking parts without the casing; and Fig. 3, a side view.

To adapt my invention to use on the face of doors, I constructthecrooked leverD, as shown in drawing, Fig. 2, with knob K, extendingoutside the casing, as shown in Fig. 3. At each end of the lever D, asshown at E E in the drawing, are attached hooks H H, connected with wirerods R R, as shown in drawing, and attached to the bolts B; one arm oflever D, to which the lower bolt is attached, being longer, to allow thelower bolt to extend farther than the upper one, when desired, and byattaching the rod equidistant thereon from the center when not.Connected with the rod to the'lower bolt I attach links, as shown at Lin drawings, for the purpose of operating the upper bolt alone, whilethe lower bolt is held by the springcatch Gf, as shown in drawing asextended or drawn, the links allowing the rod to .pass to y accomplishit. At points, as shown at F F in the drawing, I place smallfriction-rollers, over which the rods are drawn in operating the bolts.The casings of the bolts are constructed in three separate parts, forconvenience in attaching the rods, as shown in Fig. 2 in the drawing,and the lower one provided with notches, as shown 'at G in drawing, 'toadmit the spring-catch C', used to fasten it in operating. I alsoconstruct a spring or drop catch to hold the lever D in operating theupper and also lower bolt, when desired, as shown at G in drawing. Thebolts are reversible, so as to use on doors swinging out or in, or fromright or left. The fastener, as constructed, is reversible, as a whole,by simply substituting a lefthand lever, D. The casing A, to bolts,rods, lever, &c., is constructed separate, and attached in place afterthe working parts of the fastener are put on the door iuworking order.

My invention, as improved for the purpose herein mentioned, is single-acting, operated by y taking hold the knob K, at the same timeputting the toe of the boot against the springcatch C', and pressingslightly in pulling down on the knob till caught by the spring C, thespring-catch C at the same time dropping into the notch Gr in the bolt.The lower bolt now being fastened, the upper one may be operated alone,the links L allowing the lever to work without aiecting the lower bolt.

What I claim as my improvement, vand desire to secure by Letters Patent,is

The crooked lever D, catches C C', links L, and friction-rollers F, incombination with the rods It, bolts B, and springs S, all arranged onthe face of the door so as to work the bolts at either or both ends,when constructed, arranged, and operated as described and shown, for thepurpose set forth.
